Quicker than I thought, I got the last things fixed and brought the site back. Most of the changes were under the hood, fixing small tagging bugs and hopefully preventing new ones.
From the work I did today, I got the ability to do some new sorts of things with tags, like showing related tags that often show up alongside the current tag you are viewing, as well as everyone that has used the tag more than once on their posts. I built these so that you could figure out related subjects and threads, as well as find other folks interested in the same subjects you're viewing.
More stuff to come soon, but that's about all for today.
